Chapter 4 - EXPOSURE TO MERCURY

Nationally, the most important source of exposure to any mercury compound is the consumption of fish. Certain populations may have occupational exposures and in certain areas of NJ consumption of water from private wells can be a significant source of mercury exposure (see Volume II Chapter 7). The extent of exposure to mercury from cultural uses is not known and such practices appear to be limited to specific communities. There has been a long history of occupational exposure to mercury, but nationally most significant occupational exposures have ended. While dental amalgams may be a significant source of exposure on an individual bases, the health implications of such exposures are unclear. This chapter therefore will largely emphasize exposure to methylmercury from fish consumption.
